PatentedAug. 12,1919.

Application filed April 4, 1919. I Serial No. 287,408.

To'all whom it mag concern: Y

Be it known that I, DAVID L.; Wnnmcx, a citizen of the United States, residingat Harrisburg, in the county of Dauphin] and have invented a new of. whichthe following. is a specification.-

This invention relates to improvementsin sash fastenersv for windows," the object'of the invention being to proyidfe an improved fastener. thatis'adapted to lockthe sashes at any position so as to' permit'the upper and lower sashes to be raised and lowered to any desired height and at-the sametirne effectively prevent ,the'; sashes from: being further raised or lowered from the outside.

A further object of, the invention is to provide a sash "fastenertha't will securely lock the sashes at any desired point without forcing ,the' upper and slower sashes apart at the meeting rail, .and which will .efiectu'ally prevent rattling of the sashes.

With the foregoing and other objects in View, which will appear as the description proceeds, the invention consistsin the novel of parts. which will. bemore fully described hereinafter and particularly pointed out in the claims. 3

In the drawings accompanying and forming part of this specification,

Figure 1 is a. sectional view taken on the p 2, showing a port on of;

without interference with each other.

line 11 of Fig. a window sash having my improved fastener applied thereto; and

Fig. 2 is a plan view of the upper sash frame section.

The same characters of reference designate the same parts in the different figures of the drawings.

Referring to the drawings, 2 designates the side bar of the upper sash and 3 the upper cross plate of the lower sash. The fastener in the present instance comprises a base plate i provided with suitable countersunk openings for the passage of screws 5 for securing the plate to the u per cross plate 3 of the lower sash. The ase plate 4 is provided at its upper side, approximately centrally thereof, with a raised circular boss 6 and at the under side thereof with a circular depression 7 concentric with said boss. The base plate is further provided with an openin 8 passing through said boss preferably a jacent to one side of thereof, the side bar being shown in 15; for pivotally securing "on the base plate, '1.'- The opposite end of the link is of L- otally securing thebracket to the link.

the depression -7. Pivotally' mounted on- "said base plate is a brace member or link 9,.provided at one end thereof with an enlarged circular opening 10 adapted to receive a projection or boss 11 extending from a lever 12, saidlever having a shoulder 13 around said boss adapted to seat on the 'up- "p'er'sid'e of the 'link member 9. An open- 5 ing 14 passesthroughthc lever eccentrica'lly *located with relation to' the bossll and adaptedto register with the opening 8 in the base plate for the reception of a rivet the lever and link as clearly shown in Fig.

an L-shaped bracket, 16 that is provided with a projecting perforated car 17', a rivet 18 passing through the ear 1'7 and through a perforation. in the link member for-pivprevent -marri'ng of the sash frame, I provide an efficient gripping 'member 19, securved to the bracket and formed of rubber or other flexible material, glued "or otherwise secured to the bracket 16fat: the inner sid'es thereof, said gripping member-19 being preferably shaped at its outer side to conform to the shape of the side-bar 2, as

' shown in Fig. By'this construction, the

link may be pulled bodily away from. the sash so as to release the samefor permittingfthe sashes" to be moved up or do'wn When it is desired to lock the window, the lever is thrown over toward the right, the eccentric action of the boss 11 forcin the link outwardly toward the side bar g and thus clamping the bracket 16 against the side bar. It will thus be seen that the looking pressure exerted by the link is in the direction of the width of the window, so that such pressure tends to force the sash frames against the side frames of the window, and does not force the sashes apart, which is of great advantage, since such forcing apart of the sashes causes considerable strain on the comparatively slender strip at the outside of the upper sash. In fact, in the use of this device if such strip were entirely removed the upper sash would still be held securely [shaped formation and'is adapted to receive sure of the lever always against the rivet rather than against the opening in the link and renders the operation of the lever very easy.

While I have described in detail the structure herein illustrated, it is to be understood that I do not thereby limit my invention to the precise features of construction shown, as I am aware that many mechanical changes may be made Without departing from the spirit and scope of the invention as set forth in the appended claims.

Having thus described my invention,what I claim is:

1. A device of the class described, comprising a base plate, a link pivotally secured thereto, and a lever pivotally secured to said plate and link and adapted to exert pressure on the link in the direction of the length of I the link. I I

2. A device of the class described, comprising a base plate, a link seated on said base plate, and a lever seated on said link, said base plate, link and lever being connected together at a single point and said lever and link being eccentrically connected whereby the lever will be adapted to exert pressure on the link in the direction of the length of-the link.

3. A device of the class described, comprising a base, plate, a link pivotally secured thereto, a lever pivotally secured to said plate and link and adapted to exert pressure on the link in the direction of the length of said link, and a gripping member carried at the end of the link opposite its pivotal connection with the lever.

4:. A device of the class described, comprising a base plate, a link having an enlarged opening therein, and a lever having a projection adapted to fit' within said open ing, said base plate, link and lever being pivotallyconnected. together eccentrically of said projection and opening whereby rotation of the lever will cause movement of the link in the direction of its length.

5; A device of the class described, comprising a base plate, a link pivotally secured at one end thereof to the base plate, and a lever pivotally secured to the link and base plate and adapted to exert pressure on the link in the direction of the length of the link, said link being formed at its opposite end with anlangular. portion out of alinement withsaid, pivotalrconnection, and an angular bracket pivotally secured to said link and adapted to be seated within said angular portion.

. 6. In a device of the class described, the

combination with a pair of companion windowsashes, of a base plate adapted to be socured to the frame of one of 'the sashes, a link seated on said base plate and adapted to engage theframe of theother sash, said link having a circular opening formed therein, and a lever having an annular projection adapted to fit saidopening, said link and lever being pivotally secured'to said base plate at a single pointeccentrically of :said projection, whereby rotation of the lever around its pivot will cause said link to engage and disengage the frame of'the sash;

In testimony that I claim the foregoing as my ownI have hereto aflixed my signature in the presence of two witnesses I DAVID L. WEN RICK. WVitnesses:
